# Overview

> Contentful Personalization is your go-to solution for experimentation, personalization, and analytics, allowing you to show the right content to the right user.

Contentful Personalization is our solution for experimentation, personalization, and analytics, that allows you to show the right content to the right user. You can manage it all within your current content workflow. All of our capabilities come without any performance trade-offs, enabling you to focus on what matters most.

Our extensible Experience SDKs help you integrate into your Javascript-based frameworks. We support a range of functions, such as Edge-Side Rendering (ESR), Server-Side Rendering (SSR), utilities, and plugins.

Our Experience API enables you to automate workflows, send data to or from customer profiles, or retrieve analytical reports.

## EU data residency

With Contentful Personalization, all data is stored in the EU by default, except for edge-end-user profiles which reside closest to the individual user (worldwide). That can be changed by using our separate `experience.eu.ninetailed.co` domain and can be implemented by each customer (on all plans) in their frontend.

> **Info**
>
> When using our `EU` endpoint, visitors outside of the EU will experience higher latency as the edge servers are farther away than usual.
